This talk will provide an overview of the PaaS (Platform as a Service) landscape, and will describe the Cloud Foundry open source PaaS, with its multi-framework, multi-service, multi-cloud model. Cloud Foundry allows developers to provision apps in Java/Spring, Ruby/Rails, Ruby/Sinatra, Javascript/Node, and leverage services like MySQL, MongoDB, Reddis, Postgres and RabbitMQ. It can be used as a public PaaS on CloudFoundry.com and other service providers (ActiveState, AppFog), to create your own private cloud, or on your laptop using the Micro Cloud Foundry VM. I will describe the Cloud Foundry architecture, and talk about the open source development process for Cloud Foundry.

5. Moore's Law is for Hardware Only
§ Does not apply to software
§ Productivity gains not keeping up with hardware and bandwidth
§ Writing software is hard, painful, and still very much a craft

20. Cloud Stack - History
§ What does cloud mean, 4 main angles
• Software 1994 Netscape
• Infrastructure 2002 Amazon AWS
• Platform 2008 Google
• Development now!
§ Industrialization of hardware and software infrastructure
• like electricity beginning of 20th century, cf The Big Switch, Nick Carr
§ But software development itself is moving towards craftmanship

21. Cloud started at Consumer websites solving their needs
• Google, Amazon, Yahoo, Facebook, Twitter
• Large Data Sets
• Storage Capacity growing faster than Moore’s Law
• Fast Networks
• Horizontal -> Vertical scalability
• Open Source Software
• Virtualization
• Cloud is a productization of these infrastructures
• Public Clouds Services: Google, Amazon
• Open Source Software: Hadoop, Eucalyptus, Ubuntu, Cloud Foundry

22. Infrastructure
22
Thursday, February 16, 12

23. IaaS/Virtualization getting mainstream
§ AWS, Joyent, Rackspace,...
§ Open Source projects: OpenStack, DeltaCloud, Eucalyptus
§ Automation: Chef, Juju
§ Standardization? DMTF
§ Inside the Firewall, Virtualization: VMware, Microsoft, Xen, KVM
§ 50% of workloads are virtualized
§ Easy to provision, manage instance...BUT
§ Still need to manage backups, software stacks, monitor, upgrades
23

24. With Infrastructure, you still need to build your own platform
§ Need to build a distributed platform on top of you infrastructure
§ Story of the AWS meltdown from last summer
• http://blog.reddit.com/2011/03/why-reddit-was-down-for-6-of-last-24.html
• http://www.readwriteweb.com/cloud/2010/12/chaos-monkey-how-netflix-
uses.php
• http://news.ycombinator.com/item?id=2477296
• http://stu.mp/2011/04/the-cloud-is-not-a-silver-bullet.html
§ Twilio, Smugmug, SimpleGeo survived it because they built their
own distributed platform on top of IaaS
§ Enterprise customers want to consider Infrastructure like CDNs
• Multi Cloud usage
• Based on Open Source de facto standards, or full standards whenever that
happens

25. Platforms
25
Thursday, February 16, 12

26. Platforms
§ Raise the Unit of currency to be application & services instead of
infrastructure
§ Google App Engine, Cloud Foundry, Joyent, Heroku, Stax
(Cloudbees), Amazon elastic beanstalk, Microsoft Azure, AppFog
§ Single or a few languages, services
§ Start of Multi language Polyglot platforms
§ Enabler for Agile Developers -> Create Business value faster
§ Lack of standards: risk, vendor lock-in
§ Enterprise needs:
• Control, customizability
• Private/Hybrid Cloud
• Avoid lock-in
26

27. Agile Development Processes
Thursday, February 16, 12

28. Agility as a survival skill
§ Consumer software is becoming like fashion
• Phone apps, social apps, short lifetime, fast lifecycles
• Ab testing
§ Clay shirky situational apps
§ Kent Beck, Usenix 2011 Talk, “Software G-Forces”
change in software process when frequency grows
§ Cloud Platforms enables an Agile culture, driver for innovation
• Scalability is built in the platforms
• Can iterate faster
• Focus on design
§ Cloud Platforms lets developers focus on driving business value

29. Main Risk: Lock-In
Welcome to the hotel california
Such a lovely place
Such a lovely face
Plenty of room at the hotel california
Any time of year, you can find it here
Last thing I remember, I was
Running for the door
I had to find the passage back
To the place I was before
’relax,’ said the night man,
We are programmed to receive.
You can checkout any time you like,
But you can never leave!
